I have a Roku streambar pro hd/4k/HDR. No sound from Blu-ray player. Player has 1 HDMI video out and optical digital audio in ports. My TV doesn't support arc-hdmi and only 1 optical port. So, how do I get it to work.
Connect the bluray to tv by hdmi, connect the streambar pro to the tv by both hdmi and optical. The optical should send audio from other devices connected to the tv to the streambar pro. Make sure the optical cable is properly seated on both ends. Optical cables could go bad, it's glass one bad bend will crack the cable break the connection.
